Abstract

The invention relates to the technical field of high polymers, particularly a weather-resistant environment-friendly vinyl resin. The weather-resistant environment-friendly vinyl resin comprises the following components in parts by weight: 43-45 parts of bisphenol F epoxy resin, 5-8 parts of organic silicon modified epoxy resin, 12-15 parts of styrenated alkyd, 15-18 parts of methacrylic acid, 11-15 parts of acrylic acid, 5-7 parts of fumaric acid, 10-12 parts of maleic anhydride, 0.5-1 part of ethyltriphenylphosphonium bromide, 0.5-0.8 part of hydroquinone, 33-36 parts of styrene, 5 parts of flame retardant and 2-8 parts of weather resistance modifier. The prepared product has the advantages of favorable weather resistance and favorable bending modulus; and the extension at break and other mechanical properties are greatly lowered as aging proceeds.

Description

technical field [0001] The invention relates to the technical field of polymers, in particular to a weather-resistant environment-friendly vinyl resin. Background technique [0002] Unsaturated polyester resin is generally a linear polymer compound with ester bonds and unsaturated double bonds formed by polycondensation of unsaturated dibasic acid diols or saturated dibasic acid diols. Usually, the polyesterification and polycondensation reaction is carried out at 190-220°C until the desired acid value (or viscosity) is reached. After the polyesterification and condensation reaction is completed, a certain amount of vinyl monomer is added while it is hot to form a viscous Such a polymer solution is called an unsaturated polyester resin. [0003] So far, the unsaturated polyester (resin) matrix used as composite material matrix at home and abroad is basically phthalic acid type (referred to as orthophthalic type), isophthalic acid type (abbreviated as isophthalic type), bisp...
